Self-selection of diets with different oil oxidation levels in gilthead seabream (Sparus aurata)
The present research looked at the ability of gilthead seabream to discriminate between two similar diets differing only in the extent of lipid oxidation. Six groups of 4 fish (254g initial wet weight) were allowed to select by means of self-feeders between two complete diets (34.5% casein + gelatin, 14.8% fish oil + soybean oil, 24.8% dextrin and 25.9% vitamins, minerals, filler and binder) wh...

متن کاملImmune response of gilthead seabream (Sparus aurata) following experimental infection with Aeromonas hydrophila.
The Gram-negative bacteria Aeromonas hydrophila is a heterogeneous organism that causes the disease known as motile aeromonad septicaemia, which is responsible for serious economic loss in seabream culture due to bacterial infections. However, the immune mechanisms involved in this disease in fish are still poorly understood. For the purpose of this study, gilthead seabream (Sparus aurata L.) s...
متن کاملFeeding time synchronises daily rhythms of behaviour and digestive physiology in Gilthead seabream (Sparus aurata)
Feeding cycles entrain biological rhythms, which enabling animals to anticipate feeding times and so maximize food utilization. In this article the effect of mealtime on locomotor activity, blood glucose, gastric pH and digestive enzymes was studied in two groups of seabream (Sparus aurata): one group received a single daily meal at random times either during the light and the dark period (rand...
متن کاملEnvironmental Conditioning of Skeletal Anomalies Typology and Frequency in Gilthead Seabream (Sparus aurata L., 1758) Juveniles
In this paper, 981 reared juveniles of gilthead seabream (Sparus aurata) were analysed, 721 of which were from a commercial hatchery located in Northern Italy (Venice, Italy) and 260 from the Hellenic Center for Marine Research (Crete, Greece). These individuals were from 4 different egg batches, for a total of 10 different lots. Each egg batch was split into two lots after hatching, and reared...
